on-rev queries

I think I see what is going on here. The connection is being made with sqlYoga initially, but of course like every good server, on-rev drops the connection after a period of inactivity. Now normally I would execute an SQL statement through sqlYoga, but there is no function or command as yet that allows me to simply execute an SQL statement and return a result, or not that I have been able to find. 

So I have to get the database ID using an sqlYoga function, then use the rev IDE to query the on-rev database. Often, by that point, the connection has been dropped. I think the fix for this for now is for me to issue dbconn_connect every time I access the database. This would be automatic for queries done through sqlYoga, but as I said, I can't use that right now for raw SQL queries. 

One thing I should mention though that I find odd, is that the function revdb_execute() does not generate an error in a try/catch construct, even if the connection has been dropped and the command fails! Maybe someone could pick up on that and update the IDE to incorporate that.
